e 1 claim. (ci. 257-136) 'Ihis invention appertains to heat exchangedevices, and more particularly to a novel radiator, the principles ofwhich are capable of general application.

One of the salientobjects of our invention is to provide novel means forconstructing a radiator for either heating or cooling purposes,havingnovel core units for insuring a quick and uniform exchange of heatbetween liquids and 10 gases.

Another important object of our invention is to provide a radiator inwhich the heat exchange core can be readily built up, assembled in and.associated with any desired type of shell, or

casing.

A further object of our invention is to provide a radiator'including acore embodying a plurality of intertting rings, or cups, adapted to besoldered or Aotherwise connected together,

having annular outstanding heat absorbing flanges on their outer faces,and inwardly directed heat dissipating n's on their inner faces, the nsbeing staggered relative to one another for forming a tortuous passagefor the air g5 through the core so as to insure the rapid transmissionof heat thereto.

. A further object of our invention is to provide inwardly directed finson the intertting rings, or cups, arranged in staggered relation,

the fins having openings therethrough in alinement with spaces betweenthe fins of adjacent rings, whereby to permit a maximum iiow of airaround and through the ns.

A further object ,of lour invention is to provide a radiator including acore having a plurality ofinterfltting rings provided with annu- `larstop shoulders thereon to form a snug lit with adjacent rings, the ringshaving annular outstanding flanges on one of their edges, and

4o inwardly directed fins on their other edges.

A still further object of our invention is to.v provide a novel radiatorof the above character,

which will be durable and emcient in use, one

. that will be simple and easy to manufacture,

and one which can be placed upon the market at a reasonable cost.

With these and other objects in view, the invention consists in thenovel construction, ar-

rangement and formation of parts as will be hereinafter morespecifically described, claimed and illustrated in the accompanyingdrawing, in which drawing:-

Figure 1 is a bottom plan view of the radiator with the shell inhorizontal section, one of the rings of one core unit'being shown brokenaway to illustrate the arrangement of the fins of the rings relative toone another.

Figure 2 is a detail vertical section taken on the line Zz of Figure 1,looking in the direction of vthe arrows. 5I

Referring to the drawing in detail, wherein similar referencevcharacters designate corresponding parts throughout the several views,the letter A 4generally indicates our improved radiator which comprisesa shell, or casing, 5 having 10 a plurality of core units 6 mountedtherein.

The shell 5 can be of any desired construction and shape,`and, as shown,the same includes top and bottom walls I and 8, end walls 9 and sidewalls I 0. The bottom wall 8 can be made sepa- 15 rate from the bodyportion of the shell and secured thereto in any preferred manner. Theend walls 9 can be provided respectively with inlet and outlet nipplesII and I2 for permitting the flow of liquid through the shell. 20

Each of the core units 6 embodies a plurality of interitting rings I5which form the salient feature of our invention. These rings are pref--erably formed from lightv sheet metal and stamped or pressed into theirdesired form, but '25 it is to be understood that the rings can bemolded without departing from the spirit of our invention. The metalfrom which the rings are formed is preferably ofsuch a nature as torapidly conduct heat. 30 i Each of the rings, or cups, I5 includes anannular body, or side wall, I6, and this body, or wall, is oifsetintermediate its ends to provide an annular stop shoulder I1. One edgeof each ring is provided with an annular outstanding 35 flange I9, whichformsa means for absorbing heat from the liquid flowing through theshell. The other edge of the ring is provided with a plurality ofequidistantly spaced radially disposed fins I9. A11 ofthe fins areprovided with open- 40 ings 20 therethrough.

The rings are'tted one within the other, and the shoulders form seatsfor adjacent rings. The rings preferably have a press fit, and the samecan be soldered or welded together, if preferred. 45

In assembling the rings to form a core unit, the fins I9 thereof arestaggeredly related so as to form a tortuous pass for the air ilowingtherethrough. Care is taken to have4 the openings 20 of one ring inalinement with the spaces between the iins of the next ring. rIYhus,this not only allows the flow of air around the fins, but also permitsthe flow of air through the fins.

1 As shown in Figure 2, the bottom plate, or 55 wall, 8 is provided witha plurality of openings 2| for the core units, and these openings 2| arein direct alinement with openings 22 formed in the top wall 1. Anannular bead, or flange, 23 is formed around the openings 2| to providea seat for the core unit, and the annular ange of the lowermost ringfits snugly against the inner face of the plate 8 around the flange 23.

The walls of ythe, "openings 22 can berabbeted to provideshoulders 24for receiving the topmost rings of the core units, and, if desired, thetop and bottom rings of the core units can be soldered or welded to thewalls oi.' the shell.

Obviously, as the water or other liquid iiows through the shell, thesame will circulate around the different core units which are alsostaggeredly arranged. The water flowing between the annular anges I8will permit these flanges to quickly absorb the heat from the water andtransmit the same to the fins, `where the heat is dissipated to the airflowing through the core units.

It has been found that a radiator constructed in accordance with ourinvention is cheap to manufacture and assemble, and is highly efficientin use.

Changes in details may be made without departing from the spirit or thescope of our invention, but what we claim as new is:-

A core unit for radiators comprising` a. plu 10 rality of interttingrings; eachvring including' abody having an annular, outstanding flangeformed at one end and an inwardly directed ila-nge formed at theopposite end, means carried by said body forming a stop for the adjacent15 ring to 'equidistantly spaceA said flanges, the inner iianges of therings being staggeredly related to one another and provided with.'alined openings.
